There's a clear sentiment behind these words; unfortunately, the multitude of unoriginal phrases ("to lay by your side," "I'll kiss you on the lips," "I am complete"--among others) weigh this poem down severely. Your attempts at tenderness would be more effective if you'd provided the reader with specific images: what are your children doing on the lawn? What do they look like? What does your lover smell like? Things like that. The third stanza as a whole lacks originality--think: how can you show love subtly? Kissing and hugging is overdone and is nowadays unexciting when you just present it to your reader flat out. My advice is if you've got a scene in mind, paint it on the page with all the little details. Cliches and general statements don't usually work well in poetry; it's adventurous writing and specificity that does.
